POST-DOCTORAL POSITION AT EPA

Chemical Physicist/Physical Chemist with experience in the use of
laser-based spectroscopic methods for measurement of gaseous species.
The ideal candidate will have hands-on experience with resonance
enhanced multiphoton ionization (REMPI) or other laser spectroscopy of
molecules.  The candidate will work in an applied program that couples
REMPI with time-of-flight mass spectrometry (TOFMS). The candidate will
work with the leading international laser spectroscopy groups developing
the REMPI analytical method and designing and building an instrument for
use at EPA.  Candidate will apply REMPI instrument for detection of
trace halogenated air toxics as part of a comprehensive program at the
EPA's combustion research facility in Research Triangle Park, NC,
investigating the formation mechanisms of these pollutants.

Background

The U.S. EPA's Office of Research and Development, National Risk
Management Research Laboratory (Research Triangle Park, NC) conducts
research on formation mechanisms, quantification methods, and prevention
of hazardous air pollutants, particularly halogenated organics such as
chlorinated dibenzodioxins/dibenzofurans, biphenyls, and napthalenes.
Recently, NRMRL has been awarded a grant to study the application of
REMPI/TOFMS techniques toward development of a real time "dioxin"
monitor.  This grant program, combined with a DOE-funded program to
develop the instrumental science behind REMPI/TOFMS, constitutes a large
federally-funded effort whose goal is to develop this method of
hazardous air pollutant detection for source characterization,
understanding of pollutant formation mechanisms, and pollution
prevention.
As part of this program, a REMPI/TOFMS system will be built for use at
EPA's combustion research faciltiy.  The post-doctoral laser
spectroscopist is necessary to operate the REMPI/TOFMS system and
develop its application for trace halogenated species detection.
Candidate will work with a team of researchers investigating hazardous
air pollutant formation on in-house facilities including waste
combustors, industrial boilers, solid fuel combustors, rotary kilns, and
laboratory reactors.

Particulars

The optimal timing for arrrival of this post-doctoral candidate is
January-March, 2000.  This timing will allow the candidate to work with
the REMPI developer as they put together the instrument, allowing the
candidate to better understand how the REMPI/TOFMS system works.  Salary
is $48,000 per year.  This position is open to foreign nationals as well
as U.S. citizens.
